The compressor may, however, be bu it in piston reciprocetes in the cylinder i any desired size and may be used tor any and is preferably provided with the outer other purpose for which it. is t'ound applihead E and. the inner heed F connected'by 2e cable or in any connection, in which it is the reduced neck G. The piston is con 70 desired to obtain compressed air or gas free nected to the crank H/by the piston rod 5 from oil, as in the manufacture of dried and the piston and cylinder are supplied or desiccated milk, in which compressed air with oil from the crank case B, the oil beihg is commonl used to spin-y the milk'into the indicated at K. l desiccators. ,7 The cylinder is provided with suitable 75.
The primary object of the invention. is to head L having tl-ie inlet opening O and the enable the pistoninnd cylinder operative outlet P. Bet-Ween the head L and the cylpgirts to be supplied with oil by splash lubriindex A is preferably plziced a plate Q, cercntion from the-crank case, Whi e ntthe some tying the inlet valve It and the discharge time preventing an excessive amount ol oil valve S. These VZIlX'QS are preferably in the 8 3 from accumulating on. the pishon and on form of strips of sheet metal, secured to the the WilllS of the cylinder, In pumping up plate Q by means ot the screws and nuts T the pneun'uitic tires of a motor vehicle, esand U.
